A structured waste management system is vital because, in mining\noperations, the greatest risk is not merely the volume of waste, but the\npotential breakdown in the management chain, stated Eko Adhi Setiawan,\nan Energy Expert from the Department of Energy Systems Engineering,\nUniversitas Indonesia.<\/p>\n
This strategic move has driven an 11.3 per cent year-on-year decrease\nin solid waste generation. According to the MIND ID 2025 Sustainability\nReport, 82,876 tonnes of hazardous and toxic waste (B3) and 946,733\ntonnes of non-hazardous solid waste were diverted from landfills through\nvarious reuse schemes. The total amount of waste material utilised\nthroughout the year exceeded 1 million tonnes.<\/p>\n
As the utilisation of waste material increased, the total solid waste\ngeneration of the MIND ID Group fell from 1,306,835.91 tonnes in 2024 to\n1,159,049.16 tonnes in 2025. This reduction occurred across two main\ncategories: hazardous waste decreased from 270,478.08 tonnes to\n208,441.10 tonnes, while non-hazardous waste dropped from 1,036,357.83\ntonnes to 950,608.06 tonnes.<\/p>\n
This downward trend in waste generation has remained consistent over\nthe last three years, falling from 1,396,034.05 tonnes in 2023 and\n1,306,835.91 tonnes in 2024.<\/p>\n
In addition to solid waste, the report noted that hazardous liquid\nwaste amounted to 4,764.52 tonnes in 2025, comprising used oil, waste\noil, oil sludge, used diesel, used grease, and expired chemicals. Eko\nnoted that these achievements demonstrate the importance of a structured\nwaste management system as a foundation for good mining practices.<\/p>\n
According to Eko, every type of waste\u2014whether hazardous, liquid,\nprocess residue, sludge, used oil, chemical packaging, or large volumes\nof non-hazardous waste\u2014requires a clear management trail. This trail\nmust encompass the waste\u2019s origin, storage, transport, processing, and\nfinal disposal evidence.<\/p>\n
He added that the approach to utilising waste material shows that\nwaste management is no longer solely focused on final disposal, but is\nmoving towards optimising materials that still hold economic value.\n\u201cWaste is not only viewed as a toxicity issue that must be secured, but\nalso as a material stream that needs to be classified,\u201d he said.<\/p>\n
Eko argued that classification is necessary to distinguish between\nmaterials that must be strictly controlled, those that can be reused,\nrecycled, or recovered, and those that must truly be disposed of as a\nlast resort. This approach is reflected in various initiatives by MIND\nID member entities to support the circular economy.<\/p>\n
For instance, PT Aneka Tambang Tbk (ANTAM) utilises nickel slag from\npyrometallurgy processes as construction material for Pomalaa Beton\n(POTON) for road base, yard base, and internal construction needs. ANTAM\nalso processes gold tailings into Green Fine Aggregate (GMA), while Fly\nAsh and Bottom Ash (FABA) is used alongside nickel slag as raw material\nfor Pomalaa Beton.<\/p>\n
At PT Indonesia Asahan Aluminium (INALUM), internal scrap from the\naluminium smelting and casting process is reused to support production,\nhelping to reduce the need for primary raw materials such as alumina.\nMeanwhile, PT TIMAH Tbk manages Processing Residues (SHP) using physical\nmethods such as gravity, magnetism, and electrical conductivity. In\n2025, SHP reached 1,506.06 tonnes of ore, with potential for further\nrecovery through advanced processes (tin gain).<\/p>\n
\u201cSome waste materials can have value as secondary raw materials,\nmaterial substitutes, or inputs for other industries,\u201d concluded\nEko.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/mind-id-recycles-over-1-million-tonnes-of-residual-material-1783421855", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
